In Julia, an array is a data structure that contains a collection of elements of the same data type. It is similar to a vector in other programming languages, but can have any number of dimensions, allowing it to represent data in a multidimensional format. To create an array in Julia, you can use the Array
function. Here's an example:
Create Array in Julia Examples
In the example below, the Array function is used to create an array of type Int64
with elements 1
through 10
. The resulting array is then printed to the console.
julia> a = Array{Int64}(1:10) julia> a 10-element Array{Int64,1}: 1 2 3 4 5 6 7 8 9 10
You can also use the []
notation to create an array:
In the example below, the []
notation is used to create an array with the elements 1
through 5
. The resulting array is then printed to the console.
julia> b = [1, 2, 3, 4, 5] julia> b 5-element Array{Int64,1}: 1 2 3 4 5
You can also specify the type of the elements in the array when using the []
notation by placing the type in square brackets before the array elements:
In the example below, the []
notation is used to create an array with the elements 1
through 5
, and the type of the elements is explicitly specified as Int64
. The resulting array is then printed to the console.
julia> c = [Int64(1), Int64(2), Int64(3), Int64(4), Int64(5)] julia> c 5-element Array{Int64,1}: 1 2 3 4 5
